xserver crashes when using xrandr.

raffiki · 2017-05-16 08:24:09

I'm experiencing difficulty setting up multiple monitors and resizing screens with my latest Arch setup.
when resizing or adding a 2nd monitor whith xrander, xserver crashes and writes following output to the screen:

xrandr --output DP-1 --off --output HDMI-1 --off --output eDP-1 --primary --mode 1920x1080 --pos 0x0 --rotate normal --output DP-2 --off

operation not permitted. resize called... symbol lookup error: /usr/lib/xorg/modules/drivers/nouveau_drv.so: undefined symbol: exaGetPixmapDriverPrivatexinit: connection refused

I can startx again however.

graphics card: 01:00.0 VGA compatible controller: NVIDIA Corporation GP106M [GeForce GTX 1060 Mobile] (rev a1)

*(I am using DP for a 2nd monitor. Using HDMI and applying with xrandr makes both screens go black)

yeah, I didn't mention. After the crash and restart of xserver, the 2nd screen is there straight away. So that's what you see: 2 working monitors.

Docbroke · 2017-05-16 08:52:57

Sorry, but I couldn't understand what you are trying to achieve with your xrandr command. Is it just for turning off other screens?

raffiki · 2017-05-16 08:55:52

for example, yes. Or resizing 1 one of the screens. Last line of Xorg.7.log (before it crashes): [ 35740.036] resize called 1920 1080

Docbroke · 2017-05-16 09:07:41

Seems like some error with nouveau driver, I am not using one so couldn't help much there.

Lone_Wolf · 2017-05-16 09:57:29

let's see :

eDP-1 is a 3840x2160 screen (4k monitor) .

DP-2 is a 2540x1660 screen

X combines them into one big screen.

You want to disable DP-2 and switch eDP-1 to 1920x1080 mode .
Is that a correct summary ?

raffiki · 2017-05-16 10:05:59

indeed!

EXA was already not supported for Maxwell, guess this continues with Pascal.
Since glamor was dropped as well, use either the modesetting driver or the nvidia blob.

Lone_Wolf · 2017-05-17 11:09:47

Glamor wasn't dropped, just integrated in xorg server.

Try removing xf86-video-nouveau so X needs to use the modesetting driver.
modesetting and xf86-video-nouveau use almost the same parts of mesa, libdrm and kernel, so it will help to diagnose where the problem lies.

seth · 2017-05-17 12:28:11

Afaiu nouveau doesn't support implement it anymore - regadless of whether built-in or module.

Ok, so xf86-video-nouveau did drop glamor support.

I frequently read phoronix, it can be a bit biased but has decent information .
The comments often have good information , but you may have to learn to skip flamewar / troll posts to get to the interesting stuff.

It says right there "Operation Not Permitted." "Connection refused." Try running it with sudo. Something like this should at least get them running (probably not correct positions/orientations/resolutions):

sudo xrandr --output eDP-1 --auto --output DP-2 --auto
